StyleKorean Is Selling COSRX, Anua and SKIN1004 Favorites for a Flat $10 or $20 Right Now

StyleKorean just rolled out a flat price sale that drops dozens of cult K-beauty products down to a simple $10 or $20 each, no coupon math required. The retailer's own promotion page currently lists 26 items in the $10 tier and 30 items in the $20 tier, pulling from brands like COSRX, Anua, SKIN1004, I'm From, Medicube, Pyunkang Yul, iUNIK, Derma-B, Banila Co, ma:nyo and KSECRET, with some products marked down as much as 72% off their original price.

What's Actually in the Deal

This isn't StyleKorean's usual coupon stacking setup either. Most of the retailer's promotions ask you to clip a percentage off code at checkout and hope it applies to what's in your cart, which is the same format most of the other big K-beauty sites use too. A flat $10 or $20 price tag skips that step entirely, the number on the page is the number you pay, so there's less guesswork about whether a code actually worked before you hit confirm.

The sale is split into three tiers on StyleKorean's site. The ALL $10 Deal and ALL $20 Deal sections work exactly how they sound, a set list of cleansers, serums and creams priced at one flat number regardless of what they normally cost. Sitting alongside those is a Buy More Save More tier, where bundles and multi packs run anywhere from $10 up to about $68.70 depending on how many items you stack in.

A chunk of the lineup is also tagged as a Time Deal, which on StyleKorean usually means the price is only good for a limited window before it reverts, on top of whatever the flat $10 or $20 pricing already knocks off. New and Best badges scattered through the grid point to recently added items and the brand's actual top sellers, so it's not just old stock getting cleared out.

StyleKorean is running this alongside a separate event called Mega Deal Days, which works through stackable coupons rather than a fixed item list. The two promotions sit on different pages but show up on the same homepage banner rotation right now, so a cart built from the $10 and $20 Deal can sometimes pick up an extra coupon discount from Mega Deal Days on top, depending on what's in it. It's worth checking both pages before checkout instead of assuming one promotion covers everything.

Is It Actually a Good Deal?

For context, a full size COSRX or Anua serum usually runs well past $20 on its own, so seeing either brand sitting in the flat $10 bucket is a real discount, not a rounding trick. SKIN1004's Centella line and I'm From's fermented essentials show up often enough in this kind of sale that longtime StyleKorean shoppers will recognize the pattern, these are the brands the site tends to lean on when it wants a promotion to actually move units.

The catch is that StyleKorean hasn't posted a countdown timer or a hard end date on the main promotion page as of this writing, which is both good and bad news. Good, because there's no artificial pressure to buy in the next hour. Bad, because flat price sales like this one tend to get picked over fast once the better known brands start selling out of their $10 and $20 slots.

If you've been circling a COSRX or SKIN1004 staple and waiting for a price drop, this is the kind of sale worth checking before it quietly disappears. The same goes for anyone restocking a routine with smaller brands like Derma-B or ma:nyo, since those don't always get their own standalone promotions outside of events like this.

Flat price sales also make it easier to try a brand you've been curious about but haven't committed to at full price. A $10 slot is a low stakes way to test something like iUNIK or KSECRET without buying into a full routine, and it's a reasonable way to pad out a mostly empty cart to hit free shipping thresholds without reaching for filler items you don't actually need.

One thing to watch for with any flat price deal like this is sizing. A $10 price tag on a travel size toner and a $10 price tag on a full size serum are not the same value, even if the percentage off looks similar on the page. StyleKorean's grid lists sizes next to each item, so it's worth a quick scroll before adding things to the cart just because the number looks small.

KBeauty Codes is an independent site and isn't affiliated with StyleKorean or any of the brands listed here, we're just flagging a sale that's live on the retailer's own site right now. Prices, stock and exact discount percentages can shift without notice, so the StyleKorean promotion page itself is the source to check before checkout.
